BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to wind abatement devices, and more particularly to a flexible wind abatement and impact system for protecting structures, such as buildings and signs, as well as openings within structures.

2. Description of Related Art

The United States has experienced numerous weather-related disasters in the past 20 years that have each caused in excess of $1 billion in damages. In 2004, the State of Florida was subjected to direct hits from multiple hurricanes the combined effect of which resulted in damages of approximately 20 billion dollars. In 2005, hurricanes Katrina and Wilma subjected Florida and the Southern Gulf Coast to devastating damage.

In addition, population growth along the coastline of the United States has resulted in an increased risk to life and property from hurricane related damage. There are approximately 40 million permanent residents along the hurricane-prone coastline of the United States, with areas such as Texas, Florida, and the Carolinas, where hurricanes frequently strike, experiencing rapid population growth. Furthermore, many coastal areas experience substantial but temporary population increases from holiday, weekend, and vacation visitors during hurricane season.

Homes, buildings, and other structures, suffer substantial damage when storm generated winds carrying windborne debris penetrate the structures through window and door openings Hurricane shutters have long been used as barriers to protect window and door openings from the effects of storm generated winds. Equipping homes and other buildings with hurricane protection in the form of storm shutters is one of the most prudent actions one can take to protect life and property.

Accordingly, the background art reveals a number of storm shutters and other devices designed for permanent or removable installation on homes and buildings. Conventional storm shutters typically consist of corrugated metal panels affixed to the outside of a given structure. For example, U.S. Pat. No. 2,878,536, issued to Becker, discloses a shutter structure having overlapping corrugated panels. U.S. Pat. No. 4,333,271, issued to DePaolo et al., discloses a hurricane panel system for covering windows and doors wherein a plurality of corrugated metal panels are arranged in overlapping relationship to provide a protective structure. U.S. Pat. No. 5,345,716, issued to Caplan, discloses a storm shutter system comprising a combination of individual, interlocking modular elements. U.S. Pat. No. 5,852,903, issued to Astrizky, discloses a hurricane shutter comprising a pair of normally open doors that are swingable to a closed position. U.S. Pat. No. 5,911,660, issued to Watson, discloses a storm panel comprising a plurality of interlocking tiles interlocked together by a plurality of dovetail joints.

A significant disadvantage with conventional storm shutter panels is that installation of the panels over all of the window openings prevents light from entering the structure thereby darkening the interior. Accordingly, if power is lost, as often happens during severe storms, the occupants of the structure find themselves in total darkness.

Accordingly, a number of references disclosed in the background art reveal attempts to provide storm shutters that provide sufficient impact resistance while allowing light to enter to building. For example, U.S. Pat. No. 5,918,430, issued to Rowland, discloses a removable storm shield comprising transparent convex panels. U.S. Pat. No. 5,996,292, issued to Hill et al., discloses a perforated shutter system wherein at least one panel is formed of corrugations. U.S. Pat. No. 3,358,408, issued to Cooper et al., discloses an insulated light transmitting panel construction having corrugations in the side edges thereof. U.S. Pat. No. 4,685,261, issued to Seaquist, discloses a removable translucent storm shutter consisting of a ½″ thick polycarbonate sheet in an aluminum channel frame. U.S. Pat. No. 5,595,233, issued to Gower, discloses hurricane shutters formed of transparent, double-skinned panels that are strengthened by rods extending through the end channels. U.S. Pat. No. 5,457,921, issued to Kostrzecha, discloses a storm shutter wherein a plurality of corrugated shatter-resistant and transparent plastic sheets fastened to the structure using a mounting mechanism and fasteners inserted through key-way slots. In addition, U.S. Pat. No. 6,515,555, issued to Madden (a present inventor) discloses light transmitting storm shutter system for homes, buildings and the like. The Madden system provides a combination of corrugated aluminum and clear polycarbonate panels arranged in alternating adjacent and partially overlapping relation over a given window or door opening.

While storm panels are generally effective in protecting building openings, such systems are burdened by disadvantages. For example, storm panel systems are often overly complex, difficult to install, and expensive. One primary problem present with virtually all temporarily installed storm panels is that the panels are generally large and often very heavy, thereby rendering installation a difficult and time consuming task. As a result, many people, including the elderly and disabled, find installing storm panels difficult if not impossible without assistance.

In view of the disadvantages present in the art, the prior art further reveals the existence of alternative flexible wind abatement devices. For example, U.S. Pat. No. 5,937,596, issued to Leeuwenburgh et al., discloses a weather barrier kit is provided comprising double-faced tape used to bond a film to a window frame and a folded and rolled sheet of film having a stiffening band and strip of adhesive across the top. U.S. Pat. No. 5,939,658, issued to Muller, discloses a portable tactical shield system for shielding a doorway or window consisting of an armored curtain and a hook and loop fastening system. U.S. Patent Application No. 2004/0154242, issued to Hudoba, discloses a system for covering an opening in a structure includes a sheet of flexible material having opposed side edges. A thickened area and a pocket are formed at the side edges. A plurality of spaced apertures extend through the thickened area, and a rope is positioned in the pocket. A grommet assembly is positioned in each of the apertures to reinforce the apertures. A plurality of fasteners are carried by the structure and are spaced so that they can extend through the apertures.

While the flexible wind abatement devices revealed in the prior art are lighter in weight than conventional corrugated storm panels and thus have largely overcome some of the limitations referenced above, they are primarily designed and intended to cover relatively small window and door openings largely fail to provide a system that is sufficiently adaptable to secure entire buildings or other property from the destructive effects of hurricane force winds.

In that regard, the background art reveals several attempts directed to providing wind abatement devices capable of securing buildings and structures by essentially tying down the roof. For example, U.S. Pat. No. 5,522,184, issued to Oviedo-Reyes, discloses a net member positioned over the roof of the building structure with cables used to interconnect support beam members with the net to keep the net in place, and anchorage assemblies keep support beam members in place. This system fails to provide protection for the windows or doors. U.S. Pat. No. 5,623,788, issued to Bimberg et al., discloses a roof anchoring system wherein roof-engaging plates are arrayed over the top of a roof and connected by cables. Ground engaging assemblies are provided to anchor the roof-engaging plates to the ground. Bimberg does not provide protection for the sides of the structure. U.S. Pat. No. 5,819,477, issued to Gaffney, discloses a system for securing a building roof using a plurality of lines and ground anchors. Netting material is used to span the lines on the roof U.S. Pat. No. 5,983,572, issued to Laboy discloses a roof tie-down arrangement for preventing damage to a roof by attachment of support members anchored by cables.

The background art, however, fails to disclose a modular wind abatement system sufficiently adaptable to protect a wide variety of real and personal property from hurricane force wind damage. More particularly, the background art fails to provide a wind abatement system adapted for custom installation on any of a wide variety of real property (e.g. buildings and homes) as well as personal property (e.g. boats and motor homes). Accordingly, there exists a need for such a wind abatement system that overcomes the disadvantages and limitations present in the background art.

BRIEF SUMMARY OF THE INVENTION

The present invention overcomes the various limitations and disadvantages present in the art by providing a wind abatement apparatus comprising a modular system including a plurality of net components, ground & building connections, and net-to-net connection hardware. In accordance with the present invention, flexible net-like sheet components are configured and joined into a suitably sized and shaped web fitted in covering relation with a structure, such as a home, building, billboard, motor home, boat, or any other outdoor thing to be protected. In a preferred embodiment, the wind abatement system of the present invention includes a plurality of modular net component sections provided in pre-cut roll form for installation in covering relation with a structure to be protected. Individual net component sections are joined together to form suitably sized and shaped web using clamp devices. Once formed the web is secured to the ground in at least partial covering relation with the protected structure by suitable ground anchors such that wind forces are transferred to ground anchors. The present invention thus provides a wind abatement device suitable for protecting a wide variety of structures and property from damage resulting from hurricane force winds and windborne debris.

Accordingly, it is an object of the present invention to provide a versatile wind abatement system adaptable for use with a wide variety of structures to protect against wind related damage.

Another object of the present invention is to provide a wind abatement system that is inexpensive and easy to install.

Still another object of the present invention is to provide a wind abatement system that protects an entire structure or other object by virtual total encapsulation within a ground-anchored web.

Yet another object of the present invention is to provide a wind abatement system that may also be configured to protect window and door openings in a structure.

A further object of the present invention is to provide a wind abatement system of modular design allowing for a limitless range of configurations capable of protecting virtually any size or shape structure of object.

In accordance with these and other objects, which will become apparent hereinafter, the instant invention will now be described with particular reference to the accompanying drawings.

Net component 10 comprises a flexible sheet of woven material, and is preferably provided in sections for ease of handling and storage. Net component 10 is preferably fabricated and available in a variety of sizes including 10′×8′, 15′×8′, 20′×8′, 25′×8′, 50′×8′, 75′×8′, and 100′×8′. It should be noted, however, that any suitable section size is considered within the scope of the present invention. It should be noted that the preferred size of net component sections 10 disclosed above have been selected primarily for the reason that when in a roll configuration, the net is neither too heavy nor too large to be lifted and handled by a single worker. Thus, other dimensions for net component sections fall within the scope of the present invention. Net component 10 is preferably fabricated from a PVC coated polyester core yarn, and woven into a sturdy flexible sheet. Such material is available from Twithcell Corporation of Dothan, Ala. under the product name TEXTILENE (Item No. T30S10470). The net material is further characterized as having approximately 47% open face area and 53% solid face area.

Each net section 10 is preferably adapted with a plurality of grommets 12 fixed in spaced relation in proximity to the peripheral edges thereof. Grommets 12 are preferably spaced a suitable distance apart, such as 12″, 18″, or 24″ on center along each edge of net component 10. As best depicted in FIGS. 64-67, grommets may be attached through a single layer of net material as seen in FIG. 64, or through a double hemmed layer of net material as seen in FIG. 65, or through a double hemmed layer of net material with a reinforcing spline 13, such as a rigid bar as seen in FIG. 66. FIG. 67 depicts an alternate net edge configuration wherein the net is adapted with a hole such that when folded a semi-circular aperture 15 is formed and the folded edge is reinforced with a rigid bar 13.

FIGS. 34-48 depict a preferred embodiment clamp, referenced as 200, for use with the present invention. Clamp 200 includes first and second matingly connectable clamp members, generally referenced as 201 and 202 respectively. First and

second clamp members

201 and 202 are configured for mating connection with a portion of net material securely sandwiched therebetween. First clamp member 201 comprises a rigid body having a hook-shaped end 203 a mid section having a recessed notch 205 and a latching groove 207, and an opposing end defining a through bore 209. Second clamp member 202 comprises a rigid body having a generally U-shaped end 204 with first and second projecting

legs

204A and 204B, a mid section defining a projecting boss 206 and latch member 208, and an opposing end defining a through bore 210.

Clamp 200 functions to secure a portion of net material in sandwiched relation between first and

second clamp members

201 and 202 by joining the clamp members as illustrated in FIGS. 49-52. More particularly, an edge portion of net material is positioned between first and

second clamp members

201 and 202 as depicted in FIG. 49. The net material is preferably extended over the hook-shaped end such that the edge of the net material extends approximately to the center of through bore 209. Next second clamp member 202 is brought into engagement with first clamp member 201 such that hook-shaped end 203 of first clamp member 201 matingly receives U-shaped end 204 by inserted pivotal rotation of second clamp member 202. The first and second clamp members are secured by snap-fit engagement of latch member 208 on second clamp 202 within latching groove 205 formed on first clamp 201 as finally illustrated in FIG. 52. Projecting boss 206 further sandwiches a portion of the net within recessed notch 205 in a press fit configuration thereby further securing the net. Through

bores

209 and 210 are aligned in the clamped configuration to allow for fasteners, straps, hooks, cables, rope, and the like to pass through the clamp. As best depicted in FIGS. 41, 42, 45, and 46, the through bores are include a circular center portion, referenced as 209A and 210A, and elongate slotted portions, referenced as 209B and 210B extending therefrom.

Once the net is secured using one or more clamps 200 along a peripheral net edge, the net may be secured in proximity to a structure or article of property in a variety of secured configurations. FIG. 53 illustrates securing a clamp to wood using a fastener inserted through

clamp openings

209 and 210 having a first end adapted with wood threads and a second end adapted with machine threads and a wing nut. FIG. 54 illustrates clamp 200 secured to a hook. FIG. 55 illustrates clamp 200 and net 10 secured to a wall with a threaded fastener. FIGS. 56 and 57 illustrate securing clamp and net 10 using a concrete anchor 24 and ground anchor 22 respectively. FIG. 58 illustrates combined attachment of two clamp members, referenced as 200A and 200B, using a threaded fastener. FIG. 59 depicts and alternate embodiment clamp 300 wherein the clearance between respective clamp members is increased to receive overlapping net sections. FIG. 60 illustrates a net-to-net connection using aligned grommets. FIG. 61 shows two net sections, referenced as 10A and 10B, connected using

connected clamps

200A and 200B connected in the configuration seen in FIG. 58. FIG. 62 depicts use of the alternate embodiment clamp 300 attached to the middle portion of a net 10 with tension applied using a rope 40. FIG. 63 illustrates a net-to-net connection using a threaded fastener and washers inserted through aligned grommets.

The instant invention has been shown and described herein in what is considered to be the most practical and preferred embodiment. It is recognized, however, that departures may be made therefrom within the scope of the invention and that obvious modifications will occur to a person skilled in the art.
